Answer: the expression of certain genes is affected by temperature
Explanation:
For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.
For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.
Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature
Trichomes increase the chances of survival for plants living in areas with infrequent rainfall.
If a plant in a very rainy place had trichomes, it would probably adapt and remove them as time passed as they are unnecessary.
Answer:
C
Explanation:
in a semi-permeable membrane, very specific amounts of materials are allowed through. This is particularly helpful in the human body because the body can then create "charge differences" between ions. In these charge differences, neurons can fire and pretty much all movement in your body is achieved because of these membranes. They are also called selective membranes
Answer: pubic symphysis
Explanation:
The amphiarthrosis is the joint which shows limited mobility. This joint is a kind of cartilaginous joint which unites the body of two vertebral bones.
The amphiarthrosis articulation can be seen at the pubic symphysis of the pelvis. This cartilaginous joint strongly anchors the pubic region of the right and left hip bones. This region exhibit restricted mobility. The strength of this region helps in the weight-bearing stability of the pelvis during pregnancy.
